  17. 17. 3.3) Design for Breaking Planning to recover materials in order to maximize economic value and minimize environmental impacts through subsequent reuse, repair, remanufacture and recycling, so, some principles should be strictly followed to perform the this operation :
  18. 18. Design for Breaking Materials must be documented and methods for deconstruction Select materials using the precautionary principle Minimize or eliminate chemical connections Preferring to use bolted, screwed and nailed connections rather than welding Separate mechanical, electrical and plumbing systems
  19. 19. 4) TREND OF OPTIMIZING GREEN SHIP BUILDING TECHNOLOGY To optimize the marine design system , it essential to focus on saving materials, increasing work efficiency and decreasing cost. For example :  By optimizing the hull lines the ship speed will be increased, saving energy and improving the economic efficiency.  The optimization of hull structure will increase the deadweight and improve economic efficiency.
  20. 20. Trend of optimizing green ship building technology  The optimization of electric system design will decrease the length of cables, decrease the quantity of equipment and increase the quantity of section prefabrication..  As long as we emphasize the concept of green ship design, there will be many methods to be applied to optimize design.
  21. 21. 4.1) Selection of Materials To reach green shipbuilding, It is essential to select green materials.
